    Alternate Interior angles are congruent when lines are parallel. Use Angle Addition Postulate.

    I'm guessing you might have figured that out yourself. The key phrase is 'Alternate Interior angles are congruent when lines are parallel.'

    I searched all through the lesson and I can't find where they say Angles. I only do the sides! ?

    It's a property of parallelograms. That statement is really enough proof as it is. I would back that statement up with the diagram and equations; if the question pushes for more information.

    SO write "Alternate Interior angles are congruent when lines are parallel."??

    Opposite angles are congruent because correspondent angles on congruent triangles are congruent. Yes, Alternate Interior angles are congruent when lines are parallel. The question is referring to angles.
